You engage in a couple of ancient heresies, even if coined in different terms. It's a form of Patripassianism, or Monarchial Modalism. You see the Father and Son as both expressions of one Person--the Father. This is the Father separate from the Son, and the Father in the Son, rendering both "God."
But by denying the Son a human spirit he is more like a phantom than a human person. Like Docetism, he isn't really experiencing humanity, but is really the Father in a human body (this is different from Docetism).
You just go on with your perceived notions and never address the questions asked. It's clear to me the Son who was, His spirit, was in the body prepared for Him. While His spirit is not human it's also not the Spirit of the first and Last. If Jesus has a human spirit and human body what part of Him was God? And what part of the Son who was descended from above?
There is only one Spirit. Why would Jesus need to receive His own Spirit from the Father?
Acts 2
Exalted to the right hand of God,
he has received from the Father the promised Holy Spirit and has poured out what you now see and hear.
That is critically opposed to God suffering via His Son as an entire man, containing a human spirit. Without that, redemption could not have been completed.
He did suffer and committed "His" spirit into the Fathers hands. His human body died on the cross as put to death in the flesh.
The idea of an eternal Son in the figure of a God who temorarily indwelled a human body is purely nonsensical. If the Son was "God" only because of God's indwelling him, never having had a human spirit, then he never could've been "God." The "Son" was never a true man, and the man was never truly the eternal God.
Jesus is the image of the invisible God NOT the invisible God.
The fullness was pleased to dwell in Him. He is not that Deity. If He was Deity then it makes no sense to state the Fullness was "pleased"to dwell in Him. (From the will of another) A other who begot Him at some point in history before the world began. A child of God the Father.
The Spirit of the Father is living in Him without limit. He is not a expression or attribute of God He is ALL that the Father is and they are ONE.
Hebrews 1
The Son is the radiance of
God’s glory and the
exact representation of
his being,sustaining all things by his powerful word.
Prior to becoming a man he had to exist not as a man but as something else. You call him the "eternal Son" without any sense as to what this really means. For you, the Father and the Son appear to be indistinguishable. They are both the eternal God. They are both the "Father."
He existed as the Firstborn of the Father and one in whom all the fullness of God the Father was pleased to dwell.
About the Son
Why the need?
When God brings the Firstborn into the world He commands all His angels to bow to Him.
The church of the Firstborn.
God appoints His Firstborn to Davids line and Davids line is established forever.
Psalm 89 The Christ is the most exalted not David
And I will appoint him to be my firstborn,
the most exalted of the kings of the earth.
28 I will maintain my love to him forever,
and my covenant with him will never fail.
29
I will establish his line forever,
his throne as long as the heavens endure.
They shall look on the one they have pierced.
And I will pour upon the house of David, and upon the inhabitants of Jerusalem, the spirit of grace and of supplications: and they shall look upon me whom they have pierced, and they shall mourn for him, as one mourneth for his only son, and shall be in bitterness for him
, as one that is in bitterness for his firstborn.
This is modalism. The idea that God's Word can express God's Person in the finite form of the Son is simply disbelieved. The effort to explain the transfer from the infinite to finite expressions of such leads to miscommunication and misinterpretation of biblical truths, and to error.
Jesus is the Word of Life. The Word of the Father.
God has spoken to us in these last days by
His Son
Deal with it.
Don’t you believe that I am in the Father, and that the Father is in me? The words I say to you I do not speak on my own authority.
Rather, it is the Father, living in me, who is doing his work.
I call the preexistent form of the Son the "Word of God" because both his preexistent Person and his manifest human Person have in common God's ability to create and to reveal things, including finite expressions of His own Being and Person.
Word of God and the Word of the Father are the very same thing to me. It was the Fathers message Jesus spoke not His own. God, singular, spoke to us in these last days by His Son.
As such, Jesus' human spirit was part of the expression of God's Person in the form of a human person. By denying this you claim that God's Word is unable to present a human spirit who is identified as being God's Person.
Jesus's spirit existed before the world began. He is the Firstborn of the Father. His spirit is not human. He descended from Heaven, His spirit. He did not start life in Mary's womb. It's just stated so -fully human and fully God but not defined in any reasonable manner. A Mystery. If He had a Human body and a newly formed Human spirit then what part came from heaven and what part of Him was God?
This is error and heresy, in my view. Even if you have some things right, the confusion you create disrupts the good you wish to do.
Yes, I know you believe its error but you are the one mistaken.
It's God from true God. He is the begotten God, unlike His God and Father who is unbegotten.
It's begotten of the Father alone before all other things with a beginning as the beginning of the creation of God.
(His spirit) The Deity of the First and Last, the Father, that dwells in Him at God will is unbegotten. They are ONE.
And unto the angel of the church of the Laodiceans write; These things saith the Amen, the faithful and true witness, the beginning of the creation of God
